100 to 500 Ω (each) for a properly terminated low- speed network. Termination on the low-speed/fault-tolerant ports of the NI 9852 is set through the NI 985x software to either 1 kΩ or 5 kΩ. Number of CAN Nodes The maximum number of nodes depends on the electrical characteristics of the nodes on the network. - Page 13 The NI 9852 has two full-featured, independent CAN ports that are isolated from each other, and from the other modules in the system. Each port on the NI 9852 has a Philips SJA1000 controller that is CAN 2.0B-compatible and fully supports both 11-bit and 29-bit identifiers.
